What would you change on lq4

[Tahoe03mm]

Will I get anywhere close to the power with a cammed/blown 5.3 as the 6.0 equivalent?

The cammed/blown LQ4 will still be better than the 5.3.

 

[Tahoe03mm]

Do the 6.0 use bigger injectors?

 

[03_Denali]

same size as 4.8/5.3, flex engines use larger injectors.

 

[Tahoe03mm]

I have the flex injectors currently. What all would I have to swap over to keep using e85?

 

[03_Denali]

Just injectors and tune. The tune is different also. If you're not using e85 still use the injectors, as they are larger than non e85.

http://lpparts.com/store/page7.html these headers won't worth with the 6.0? If I have a magnaflow cat-back right now and I want headers and to eliminate the cats with a y-pipe am I going to need custom exhaust?

 

[03_Denali]

yes, they will work with a 6.0. Denalis and Escalades didn't have a Y pipe, (I cant speak for the Sierra Denali, Silverado SS, or VHO) they have 2 separate down pipes that entered into a dual in muffler. But yes, everything will bolt up.

looks like i'm picking up a full lq4 setup with about 35k miles on wednesday... I was trying to get it for $700 so we'll see. I can sell the extra parts off it I don't need I suppose.
